[Subconscious image recognition].
Two experiments demonstrate the influence of an unconscious form of information storage on behavior. In the learning phase, subjects see pictures in which other pictures or figures are embedded. The experimental procedure makes sure that these embedded figures cannot be seen (or consciously identified) by the subjects. Nevertheless, the results of a perceptual identification task in the test phase prove that information of these unidentified figures has been stored by the subjects: In a clarification task, subjects were shown the cut out, previously embedded figures and other pictures which they had to name as quickly as possible. The experimental group, which had seen the pictures with the embedded figures in the learning phase, was much quicker in responding to the naming task than the control group, which had not seen these pictures before. These results are discussed in terms of a distinction between sensori-perceptual and conceptual information storage in humans. Conceptual information is characterized as meaningful, symbolic, and accessible to conscious reasoning and remembering, while sensori-perceptual information is seen as nonsymbolic, modality-bound, and restricted to unconscious reactivations in data-driven process repetitions.
